What are the values of a, b and c in the quadratic equation -2x^2+4x-3=0?
AlladinOne [14]

Answer:

a=-2\\b=4\\c=-3

Step-by-step explanation:

In a quadratic equation in the Standard form

ax^2+bx+c=0

You need to remember that "a", "b" and "c" are the numerical coefficients (Where "a" is the leading coefficient and it cannot be zero: a\neq0).

You can observe that the given quadratic equation is written in the Standard form mentioned before. This is:

-2x^2+4x-3=0

Therefore, you can identify that the values of "a", "b" and "c" are the following:

a=-2\\b=4\\c=-3

Item 1 The value of a car is $23,000. It loses 11.1% of its value every year. Find the approximate monthly decrease in value. Ro
IrinaK [193]

Answer:

<h2>$212.8</h2>

Step-by-step explanation:

If the car loses 11.1% per year, we need to calculate how much money is that:

23,000\frac{11.1}{100} = 2,553.; this value is the lost per year.

Now, in order to calculate this loss per month, we divide it by 12:

\frac{2553}{12} =212.75

Hence, the monthly value decrease is $212.8, rounding it to the tenth.
